Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979542, here are decompositions:

13 + 979529 = 979542
23 + 979519 = 979542
61 + 979481 = 979542
71 + 979471 = 979542
103 + 979439 = 979542
139 + 979403 = 979542
163 + 979379 = 979542
173 + 979369 = 979542

Showing the first eight; more decompositions exist.
